Abstract

L'invention concerne un procédé de traitement semi-centralisé et de préparation de courants de matières biogènes dans des systèmes d'aménagements agri-urbains en utilisant et/ou en transformant les biomasses organiques liquides et solides, par exemple les eaux usées, les biodéchets, les résidus des récoltes, les déchets verts et autres résidus biogènes sous forme d'économie circulaire. Le procédé comprend un recyclage des eaux noires au cours duquel les eaux noires sont d'abord soumises à une filtration préalable sur au moins un filtre organique de sorption (6) afin de recevoir les matières organiques et les engrais des eaux noires dans un mélange de matières de filtration. Les matières organiques et les engrais contenus dans les eaux noires restent dans le filtre de sorption organique et les eaux noires ainsi préalablement filtrées sont ensuite étalées sur un filtre de sol (14) pour eaux noires consistant en un ou plusieurs bassins et/ou récipients et/ou plates-bandes étanchéifiés, sur une plantation, sur un substrat de filtration, sur un système répartiteur et sur un collecteur ainsi que dans une citerne agencée sous et/ou à côté du filtre de sol pour eaux noires afin de stocker les eaux noires épurées et les eaux filtrées à travers le filtre de sol pour eaux noires sont ainsi disponibles pour l'irrigation des plantations ou des espaces verts. On a en outre prévu un recyclage des eaux grises dans lequel on étale les eaux grises sur un filtre de sol (30) pour eaux grises. Les eaux filtrées à travers le filtre de sol pour eaux grises sont d'abord épurées pour être ensuite utilisées comme eau courante et/ou comme eau destinée à l'irrigation (16).
